After two years of war and dire food shortages, more than 54,600 children younger than 5 in Gaza may be acutely malnourished, with more than 12,800 severely affected, according to a new study by a U.N. agency. By early August, roughly 16% of children ages 6 months to just under 5 years in Gaza were suffering from a life-threatening type of malnutrition known as acute wasting, including nearly 4% with severe wasting, according to the analysis by the U.N. Relief and Works Agency for Palestine
